Title: Plug socket
Inventor: TATSUO YOSHIYUKI
IPC: H01R13/11
Filed: 1988-05-26
Abstract: PURPOSE:To improve the strength of a contact piece and reduce the gradient of a plug tooth by providing the contact piece on a terminal assembly integrally and regulating the gradient of the plug tooth. CONSTITUTION:A tooth rest spring 7 formed on the end part of a terminal assembly 3 is provided integrally with a contact piece 16. The contact piece 16 is disposed between the end parts of the double spring plate 7a of the tooth rest spring 7. When the plug tooth 19 of a plug 18 is inserted into a plug tooth inserting port 13 and made into contact with the spring 7, the plug tooth 19, if inclined, is touched in the end part by the contact piece 16, which regulates it so that the gradient is reduced. An earthing terminal part of a plate form is formed by bending at the lower important point of the terminal assembly 3 in the direction crossing at a right angle to the longitudinal direction of the contact plate. The spring 7 facing the terminal part repells the earthing wire spring to the terminal part to make into contact therewith. The joint of the terminal part and the conductor is released by a release button. The miniaturization can be achieved by providing the spring 7 and the release button below the terminal assembly 3.

Abstract: PURPOSE:To produce the solidifying material with which soft soil. etc., can be solidified into lightweight soil used for ground improvement, embankment, back fill materials, etc., and a muddy material such as sludge, etc., can be converted into useful soil by mixing a cement based solidifying agent and a threshing waste such as chaff, etc., together. CONSTITUTION:This production has three features: (A) firstly, mixing a cement based solidifying material and a threshing waste such as chaff, etc., together; (B) secondly, using a ground threshing waste as the threshing waste in (A); and (C) thirdly, grinding the threshing waste such as chaff, etc., together with cement clinker in the same equipment as the cement clinker grinding equipment in the process for grinding the cement clinker. By the first feauture (A), the chaff (or the like) is hardly scattered since it is mixed beforehand and therefore, an accurate mix proportion can be obtained. By the second feature (B), the separation of the cement based solidifying material and the chaff (or the like) from each other material can be inhibited to obtain a hardened material having a fine structure and therefore obtain improved mechanical characteristics such as shear strength, etc. By the third feature (C), the objective solidifying material can be produced in a factory for producing a conventional cement based solidifying material without drastically changing the equipments of the factory.

IPC: H01L21/31
Filed: 1987-05-25
Abstract: PURPOSE:To prevent defects in a device due to hillocks, by starting the growth of an interlayer insulating film from a temperature, at which the hillocks are hardly yielded, as the temperature condition of a semiconductor substrate, and increasing the temperature in multiple steps or continuously. CONSTITUTION:A heater 13 heats a semiconductor substrate 16. The heater 13 is provided so that the surface temperature of a semiconductor substrate 16 is changed in a range of about 250-400 deg.C when the substrate 16 passes beneath gas introducing ports 14.

The forming temperature of the interlayer insulating film is started at about 250 deg.C, at which hillocks are hardly yielded, and slowly increased to about 400 deg.C. Therefore, the hillocks 33 are not extruded on a photoresist film 34 when a contact hole 35 is provided. Holes are not opened in the interlayer insulating film 32 at the hillocks 33. Therefore, a second wiring layer is not brought into contact with the aluminum wiring 31 at a part other than the contact hole 35.

Abstract: PURPOSE:To dispense with an ion current power source and simplify the structure of an ion current detecting current by detecting the ion current flowing from the earth to a center electrode with the ion current detecting circuit when the spark discharge voltage has the minus polarity. CONSTITUTION:When an ignition circuit 10 is operated, a primary current interrupting device B interrupts the primary current of an ignition coil C at the ignition timing.

A spark discharge is generated in a spark discharge gap G1, and the air-fuel mixture in a cylinder is ignited. When this ignition is normally conducted, the electrical resistance value R near the gap G1 is reduced to the generation level of the ion current. A high-level ion current shown by an arrow 7 flows from the earth S to the center electrode 24. The change of the ion current is detected as the voltage change at the V1 point of the inlet of a voltage detecting circuit 62.
